Review: Midterm Exam Content
CMN Model• What are the three processors in the CMN model?
• What is Bloch’s law?
• What is the capacity of working memory?
• What are open loop and closed loop?
Prof. Dr. Jan Borchers: Designing Interactive Systems I • WS 2019/205
Fitts’ Law• Write down the Shannon’s formulation of Fitts’ law
• How is the Shannon’s formulation an improvement over the original Fitts’ law?
Prof. Dr. Jan Borchers: Designing Interactive Systems I • WS 2019/206
Gestalt Laws and Information Content• What are Gestalt laws?
• What are some of the Gestalt laws?
• What is information content?
Prof. Dr. Jan Borchers: Designing Interactive Systems I • WS 2019/207
Design Principles• What is visibility?
• What are signifiers and affordances?
• What is feedback?
• What are mappings?
• How can we achieve natural mappings?
Prof. Dr. Jan Borchers: Designing Interactive Systems I • WS 2019/208
Spatial vs. Perceptual Analogies• Spatial analogy
• Controls are arranged in the same spatial layout as the objects they control
• Move controls in the same direction you want to move the object
• But: Control does not look like the object
• Perceptual analogy
• Control looks like the object and you interact with it using a metaphor
Prof. Dr. Jan Borchers: Designing Interactive Systems I • WS 2019/209
Constraints and Conceptual Models• What are constraints? Types?
• What are forcing functions? Types?
• What are conceptual models?
Prof. Dr. Jan Borchers: Designing Interactive Systems I • WS 2019/2010

Seven Stages of Action• What are the seven stages of action?
• What are the two main types of gulf?
• How do you bridge them?
• What are the three levels of processing/design?
• Why is it important to know about them?

When Does a Gulf Occur?• For the sake of usefulness, consider something a gulf when you find that it can
be fixed by a re-design.
• This should accommodate almost all problems a user faces when performing a task. ;)
• Example: “Krishna wants to use Siri on his iPhone, but cannot understand the language.”
• Gulf between Perceive -> Interpret, can be fixed by adding support for the language.
